Planners and engineers, not a pitch team
The people who scope your study are the people who run the analysis and sign the report. No handoff, no junior bench learning on your budget.
Transportation engineering and planning
Every crash, delay and detour was measurable before it happened.
LSC Nexus studies how intersections, corridors and networks actually perform, then plans, analyses and designs the changes that make them safer and more reliable, for people walking, cycling, riding transit, driving and moving freight.
Intersection study
Illustrative
- Control delay
- 41.6s/veh
- Conflict points
- 32
- Peak-hour LOS
- D
A worked example, not a past project. Conflict-point counts are the standard figures for a four-leg intersection and a single-lane roundabout.
The firm
Nobody sets out to build a dangerous intersection. They get built anyway, one reasonable decision at a time.
The counts, crash records, signal timings, speed data and public complaints that would have caught it are usually already sitting in an agency's files. Our work is to read them together, model what changes, and hand back a recommendation that survives review, council and the public meeting.
Built for public work
We write to the methods your reviewers expect and hand over the data, models and assumptions, so a finding can be checked rather than taken on trust.
Engineering under licensure
Planning, analysis and study work is delivered by our own staff. Work that constitutes the practice of engineering is performed under the responsible charge of a licensed Professional Engineer, in house or through our teaming partners.
A technology practice inside a transportation firm
Modelling, GIS, dashboards and applied AI are run in house rather than subcontracted, which is why our studies tend to leave a working tool behind them.
Practice areas
Six ways we're asked in.
Most engagements combine two or three of them. The full service list is below.
Transportation planning
Corridor and small-area studies, multimodal and long-range plans, transit and active transportation planning, comprehensive plan amendments, parking and access management.
- Corridor studies
- CPA studies
- Multimodal plans
Traffic engineering & operations
Traffic impact analysis, capacity and level-of-service, signal warrants and timing, turn lane warrants, queuing and speed studies, and the exception requests that go with them.
- Impact analysis
- Capacity & LOS
- Signal warrants
Safety & human factors
Crash diagnosis and countermeasure selection, road safety audits, Safe System and Vision Zero action plans, plus the ergonomics side: sight lines, sign legibility, driver expectancy and wayfinding.
- Crash analysis
- Safety audits
- Human factors
Roadway & traffic design
Signal design, signing and pavement marking, geometric layout of intersections and roads, roundabouts, traffic calming, bicycle and pedestrian facilities, and accessible design.
- Signals
- Roundabouts
- Signing & marking
ITS & smart mobility
Concepts of operations, signal system and TSMO support, detection and field data, connected and automated vehicle readiness, and keeping deployed systems reporting once the ribbon is cut.
- ITS ConOps
- Signal systems
- TSMO
Modelling, data & digital delivery
Travel demand modelling and microsimulation, GIS and spatial analysis, count and probe data programmes, dashboards and public-facing map tools, applied AI for detection and forecasting.
- Simulation
- GIS
- Dashboards
Adjacent practice
Freight, logistics & supply chain
Freight is one mode among several, and it is where a transportation network meets a business. We plan truck routes and freight corridors, and we take on standalone supply chain work: network and route design, warehouse and inventory flow, carrier and vendor evaluation, and 3PL/4PL coordination for organisations without an in-house logistics function.
- Freight planning
- Truck routing
- Network design
- 3PL/4PL
Studies, planning, analysis and modelling are delivered by LSC Nexus staff. Deliverables that constitute the practice of engineering, including sealed drawings, are prepared under the responsible charge of a licensed Professional Engineer, in house or through our teaming partners. We will say which arrangement applies before a scope is signed.

How we work
Four stages, usually in this order.
Sequence matters. We don't analyse before we can see the ground truth, and we don't leave before your staff can rerun what we built.
Stage 1
Define
One working session to state the question as a decision: which intersection, which corridor, which policy, and what has to hold up when it's challenged. You get a written scope with a fixed fee.
1-2 weeks
Stage 2
Observe
Counts, crash records, speeds, signal timing, probe data and a site visit. Where the data doesn't exist, we collect it. Most studies are only as good as this stage, so it comes before any promise.
2-4 weeks
Stage 3
Analyse
Operations, safety and modelling work run in the methods your reviewer expects, with the alternatives compared on the same basis rather than the preferred one written up alone.
3-8 weeks
Stage 4
Recommend
Report, exhibits and drawings for review, council or public comment, with the data, models and assumptions handed over so your team can rerun them next year without calling us.
Ongoing, optional
Leadership
Three principals.
Chief Executive Officer
Adewumi Augustine Adepitan
Adewumi leads the transportation practice and client engagements: study scoping, technical direction, contracts and delivery.
Chief Technology Officer
Ayo Ajiboye
Ayo owns everything technical: software and web development, data analytics, AI and machine learning.
Managing Director
Shina Enitan
Shina is chairman of the board. He provides governance and strategic oversight, and holds the firm to its operating standards.
Registrations, professional credentials and teaming arrangements are available on request and are stated in full in any proposal we submit.
